ApolloGreat comfort and supportI bought my first pair 6 years ago. They're very comfortable. The support is excellent. My legs and back are never sore. The steel toes have kept me from injury a few times.I'm on my feet most of the day. They're adequate for cold winter days with boot socks.

JimLocusDurable and ConfortableBought a pair in 2015 for outdoor use on my lake property which is hilly, rocky, wet, soggy and muddy. They’ve taken a lot of punishment including inadvertent steps into deep, wet mud. Held up great so far, confortable to wear for long work periods, never leaked. Bought a second pair for backup,but no sign that I’m going to need them in the foreseeable future! Great product and the best work boots I’ve ever owned. Nothing else has been as comfortable or lasted so long!

Eddie970The Boot I Didnt Know I NeededWas slightly larger than any normal 8.5 I wear but an extra pair of socks fixed that problem immediately. Comfort is out of this world and feels durable without feeling too rigid.

RunbncGood shoe but not for meThe shoes initially felt great. However, I did experience some discomfort in certain areas of my feet after couple days of work. The shoe itself is very nice and stylish. I’m not a fan of high tops but I wanted to give this shoe a try due to the positive reviews.
